This circuit is based on two commonly used IC that is NE555 timer and CD4017 IC with few more components. 555 timer IC wired as an monostable oscillator. In this circuit NE555 monostable generates a clock for the circuit, which provide a oscillating wave to the output pin 3 of 555 timer. Monostable or one short multivibrator has only one stable state and we have to trigger it externally to return it back to its original state. And CD4017 is a CMOS counter/ divider IC . It take clock signal from the clock input and turn on the 10 output in sequence, each time when it receives clock input pulses.
Now output from pin 3 of 555 timer is provided to CD4017 decade counter pin 14, which provide a clock pulse for the working of CD4017. Here after receiving the clock input CD4017 starts its counter from zero (as it has inbuilt counter). And it advances one by one each time pin 14 goes high (as we clap in front of Mic). Like for first clap we get output from pin 2 that is Q1 and LED1 will glow and on second clap we get output from pin 4, LED2 will glow and LED1 become off and so on. You have to connect individual relay at every output (for demonstration I have used single relay).
